Successive approximation type A / D from the comparator, D / A converter, comparator register SAR, clock generator and 65 datasheet and control logic circuit, it samples the input signal is continuously compared with the known voltage and 65 price and then converted into a binary number. shown in Figure 10-8, when the measured voltage Ux analog input to A / D, it first compares the reference voltage UR, the reference voltage is the voltage of a standard binary weight. When UR> UX, the logic control system will just add to the "code" rounding, but if UR> UX, the reservation will just add the code. This successive approximation approach, ultimately UR UX (a difference of a quantization error). At this time, A / D of the digital output corresponding to the reference voltage UR final value, it represents a measured anal...
